Axle and bearing for grain-seeding machines.



UNITED STATES PATENT OFFICE.

CHARLES L. FOWLE, OF DOWAGIAC, MICHIGAN, ASSIGNOR TO THE DOWAGIAO MANUFAC- TUBING COMPANY, OF DOWAGIAO, MICHIGAN.

AXLE AND BEARING FOR GRAIN-SEEDING MACHINES.

To all whom it may concern:

Be it known that 1, CHARLES L. FowLn, a citizen of the United States, residing at Dowagiac, (lass county, State of Michigan have invented certain new and useful Inc-- I rovements in Axles and. Bearings for Graineeding Machines, of which the following is a specification.

This invention relates to improvements in ticularly the class known as broadcast seeders, which are usually from eleven to fourteen feet in width. The result is that great strains are placed upon the carrying-wheels on account of the Wabbling motion of the machine when in use, resulting in rapid wear es ecially in the common type where the w eels revolve on fixed axles or spindles.

The main object of this invention is to provide an improved axle and bearings for the carrying-wheels of' seeding machines and grain drills, which is very stron and rigid,

and also one which is very durab e.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a detail longitudinal section of a structure embodying the features of my invention, taken on a line corresponding to line 22 of Fig. 2; Fig. 2 is a cross section, taken on a line corresponding to line 2--2 of Fig. 1, a portion of the dust cap of the inner bearing being broken away to show structural details; Fig. 3 is a detail cross section, taken on a line corresponding to line 33 of Fig. 1 Fig. 4 is a detail cross section, taken on a line corresponding to line 4-4 of Fig. 1.

In the drawing, the sectional views are Specification of Letters Patent.

Application filed January 2, 1908.

Patented April 7, 1908.

Serial No. 408,896.

taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, I have illus trated portions of a grain box comprising a bottom 1; side walls 2; and end walls 3. The end wall is preferably formed of castiron and is provided with an inwardly-projecting sup porting flange 4 for the bottom and sides of the box. On the end of the box, and preferably cast integral. therewith, is a bearing 5. This bearing is preferably arranged to project into the box so that it clears the bottom thereof. In the box, and in alinement with the bearing 5, I arrange an inner bearing 6. This inner bearing is preferably su ported by a bracket 7 secured to the side wal s of the box, so that it is supported clear of the bottom.

The axle S is preferably of uniform diameter from end to end, so that either end be inserted in the bearings, the outer erfd" being adapted to receive a wheel, as 9. The axle 8 is preferably provided with a transverse hole 10 at each end, the hole in the outer end of the axle serving to receive the key or pin 11 by which the wheel is secured to the axle. The hole in the inner end of the axle, which is arranged so as to project through the inner bearing receives the retainin pin 12, a thrust washer 13 being arrange between the pin and the bearing.

this prevents the withdrawal of the axle.

Should the axle become worn, it can be readily reversed.

The dust cap 14 is provided for the inner bearing and is preferably adapted to retain the pin 12. This dust cap is preferably adapted to receive such inthrust as there may be on the axle when a pin or other retaining means are not employed at the outer ends of the axle. Between the bearings, I arrange a housing 15 for the axle, this housing being preferably in the form of a pipe with its ends inserted in the bearing, so that it is carried thereby. This forms an effective protection for the axle from the grain and dust; and, by arranging the axle as I have described, it does not in any way interfere with the feeding of the grain through the discharge openings 16in the bottom of the grain box. The bearing 5 is preferably provided with a bushing 17, the bushing illustrated being formed in sections. This bushing is adapted to be inserted into the bearing from the outer end thereof. By thus forming and arranging the parts, I secure a bearing whlch is capable of carrying very heavy loads, and

one which is very durable; at the same time, it is not expensive to produce, and, should the axle for one of the bearings become worn, it may be readily renewed.
